Does anyone here have experience with washable nursing pads? How are they compared to disposable ones? First time mom here :)

I've read several good reviews about this washable nursing pad brand called Bamboobies and this online shop offers the product: http://babymama.ph/products-page/bamboobies-nursing-pads-multi-pack-6-regular-pads-2-overnight-pads-assorted/ According to reviews, nursing moms love it so much because of the materials put together in it: organic cotton and bamboo rayon velour with an inner layer of hemp and organic cotton, these nursing pads are ultra-absorbent and ultra-eco. I just wished I knew it when I was still bfing as I love the fact that it's heart-shaped meaning it will fit better to your boobies unlike the regular round ones plus it's thin and not bulky unlike the disposable ones.
